The former 25-watt, 375 kHz" EMC" - Winnemucca, Nevada (off-air since 2002). Photo by Stephen P. McGreevy, June 1987. Winnemucca Mountain is in the 
distant background. 


Non-directional beacon (NDB) photography: The following is a gallery of non-directional beacon (NDB) photos taken during several road-trips between 
May 1984 and December 2008, mainly of NDB's in the West, Intermountain regions, and High Plains/Prarie regions of Canada and the United States. There 
are also photos of other longwave installations, too. Probably over 2/3rds of the U.S. NDB's pictured here are now off-the-air, so these photos can be 
considered historical, especially for DXers who have logged them in the past when NDB-band-density was vastly-higher, pre-GPS implementation. 


Very useful NDB identification and logging websites:

a 


Rev. 7/ 





Map of US DGPS data-stations by frequency in kHz and location (generally uninteresting FSK at 100 or 200 baud unless you're into decoding these things, 
but they are/were useful for signal-propagation observations). Many/most are off-air late 2017 now (all but the BLUE-marked USCG DGPS beacons are 

off-air in 2018, now freeing up many NDBs into audibility again! Example - the lovely 305 RO-NM/ONO-OR Mixture is in the clear now - Bakersfield's 305 
kHz DGPS for the (Caltrans)(CA-DOT) is off-air now, as is Essex 298 photo way-below.)

355 RK Reykjavik, Iceland is located at a golf course on the tip of the Seltjarnarnes Peninsula in Seltjarnarnes, Iceland, a suburb of Reykjavik to the west of the 
downtown CBD. This beacon employs a two-guy-cable-supported "T" antenna (Marconi type) consisting of a single cable up-lead and flat-top section. Photo taken 
by Stephen P. McGreevy 09 December 2016 on a long walk and during a 12-day natural ELF-VLF research trip and a LW/MW DXpedition, also. RK is 1020 Hz 
ident-tone USB only (at the time of my visit), with a USA-style ident (no DAID). I was staying in a private apt. 10 km from this beacon, and on this fine, mild day, I 
walked to the Seltjarnarnes Nature Preserve and golf course in Seltjarnarnes, Iceland. As I loved the long nights replete with full-moonlight and loads of pretty 
Christmas Lights, and I saw three nights of level 2-3 aurora... as such, I was extremely pleased and hugely enjoyed my visit and consulting-time there. The first 
overseas NDB I have visited. Initially, I heard it on an ELF rx. as it was nearby my listening spot. Curious, the next day I walked to this beacon. Next to it to the east 
about 100-meters away is a vertical, self-supported lattice-mast near-identical to 320 YQF Alberta, Canada and 254 SPK Nevada but also included an elevated- 
counterpoise very similar to 320 HTN (pics below, and the former RK-mast is very visible on Google Earth/Apple Maps). That was the former NDB for RYK 
(airport), now this 355 kHz 'RK' unit and antenna seen at the golf course. Parking is just 100m away, and this is an easy NDB to visit and is in a lovely coastal 
peninsular location!

368 SX Cranbrook (Skookumchuck), British Columbia. Tall vertical mast antenna. Beautiful Autumn foilage next to the beacon, with the a bit of the Canadian Rocky 
Mountains visible in the background. Gail and I spent many hours trying to find this beacon! High-power and located well away from the main Highway 93. A strong 
signal in California but often battling it out with stronger ZP Sandspit, B.C. - (both were 1020 Hz USB pitch modulation when I wrote this in 1999, now SX and ZP 
are 400 Hz pitch modulation as of 12/05 - monitor 368.4 kHz). S. McGreevy, photo taken September 1993. 368_sx.jpg, 62,466 bytes.

368 VX, 
Dafoe, Saskatchewan. Medium-height, guyed antenna mast (mimicking a small mediumwave BCB station operating around 1600 kHz). Photographed near sunset as 
we drove right by it, I didn't immediately recognize it as an NDB, and we kept on driving for a few km before I thought to check the longwave portable to see if was 
an NDB - sure enough, it was (!), so we drove back to take pictures. VX is located far from any airport, etc., in a field with nothing else around. While we visited this

353 - SE (later "5F"), Fox Creek, Alberta. Just another example of a typical low-power 
(usually 25-watt) Canadian number/letter ident beacon usually found at small airports (see 328 5J photo just below). I photographed this one from afar, through 
binoculars, from the entry road to the airport, being on my way south on Hwy 37 with the goal of Waterton Park in southen Alberta at the end of the day (and it was 
threatening to rain). S. McGreevy, June 1996. 5E_353 jpg 28,855 bytes. (SINCE THIS PHOTO WAS TAKEN 5E CHANGED IDENTS TO "5F")

224 DN - Dauphin, 
Manitoba. This beacon is a fine example of a Canadian NDB employing a medium-height lattice antenna mast and drooping wire-capacitance tophat/umbrella (a 
mini-version of former Omega-D North Dakota and many Loran-C installations!). This (400 Hz USB ident modulation pitch) beacon was spied right along the 
Highway south of Dauphin - we were not DFing it. I've heard this one in California regularly when conditions to Canada are good (monitor 224.4 kHz in narrowband 
CW/SSB mode). S. McGreevy, September 1993. DN_224 jpg 32,757 bytes.

307 M5 - Manning, Alberta. Very similar installation to SE and 5J above. I saw 
this one at the airport right next to the Mackenzie Highway as I was traveling southward, and turned off the highway into the airport to take this photo in the rain. I 
didn't know what this beacon was until I checked my Sony portable. Seemed a weak signal even close. S. McGreevy, June 1996, driving southward during my Solar- 
Minimum Natural VLF Radio recording expedition (featured recordings are on my 2000 album: 'Auroral Chorus II'). (Initially, I thought this beacon was 306 kHz via 
my ICF-7600D as I had no beacon listing of it with me on the trip.). M5_306.jpg 23,902 bytes.

N5 224, Rocky Mountain House, Alberta. Gail and I drove right to the

239 O) - High Level, Slberta, (taller antenna mast on right) taken from Mackenzie Hwy. (McGreevy 6.96) 





(former - possibly off-air early 20187?) 239 OJ, High level, Alberta. This 
photo was taken while (90 km/h) in-motion southbound on the Mackenzie Highway returning from the Northwest Teritories. I had previously spied this beacon while 
driving northward to the NWT, so I was prepared to take this quick (tilted) shot as I passed by it again. The beacon antenna is the taller mast on the right (telephone 
tower is the left one). I wish I had taken the time to visit this site. Weak to occasionally fair 2-hop signal in the S.F. Bay Area and eastern California, it is a quite- 
strong 1-hop signal (400 Hz USB ident modulation) in southern (Lakeview) Oregon where I also resided and monitored it (on 239.4 kHz narrowband CW/SSB 
mode) for good northward conditions. S. McGreevy, June 1996. OJ_239 jpg, 31,810 bytes. 





| (former) 320 YQF, Red Deer, Alberta. This strong, high-power NDB uses a tall self- 
ipponne mast similar to many U.S. NDB's eval the eae LOM/ formerly-TWEB beacons). Similar antenna mast to 239 OJ - Alberta and 320 HTN 
Montana (see HTN below). Gail and I drove many miles out of our way to find this beacon, but could not get closeer than this somewhat distant shot. Strong signal 
throughout western North America with 400 Hz USB ident modulation pitch (monitor 320.4 kHz in narrowband in CW/SSB mode) S. McGreevy, September 1993.

4g tote 311 kHz 9Y Pincher Creek 
airport, Alberta. Taken on 04 July 2001, this pretty beacon is located at the Pincher Creek airport. I drove right by 9Y on my way into Pincher Creek in order to get 


my van's oil-seal fixed there. This beacon employs the uppermost of three or four guy wires as its capacitance umbrella, as do many Canadian NDB's. It can be heard 


on its 400 Hz USB ident at 311.4 kHz between the US DGPS beacon data streams. Sometimes HY Hay River NWT accompanies it in good conditions. Last logged 
in the desert of Calif. Christmas morning 2005. S.P. McGreevy

—— 7 540 
CBK Watrous, Saskatchewan (CBC-1). Returning southward from northern Saskatchewan after my VLF Recording Expedition, and on my way toward Waterton 
Park, Alberta, I van-camped 10 miles from CBK. The next morning 03 July 2001, I stopped by this great AM/MW radio station to take some more pictures, 
augmenting my photo collection of CBK from September 1993. 540 CBK has a gorgeous-looking white and blue painted building to the east of Watrous; their 
formerly-used open-feed has been replaced in-usage with the thick, black coaxial hard-line cable; and CBK has the largest groundwave coverage of any North 
American AM-BCB station (the second largest is 550 KFYR Bismark, North Dakota with 5 kW) - on a good car radio, the daytime groundwave from 540 CBK is 
clearly listenable from the foothills of the Rockies in Alberta well southward into the Great Plains of central South Dakota and northward up to the NWT border from 
experiences via eight road trips. Nighttime reception can be clear even in Hawaii, if western Samoa or XEWA San Luis Potosi, SLP, Mexico (etc.), are not 
interfering. During my travels in Sask. I noticed quite a number of residents tuning into CBK all over the Province - CBK's great coverage is important to the 
Canadian Broadcasting Corporation (CBC). (Local ground-conductivity at Watrous/CBK exceeds 30 mmhos! Contrast that with 0.3 mmhos ground-conductivity 
calculated in the Hilo, Hawaii [lava-geology] region from the 1060 KAHU signal measurements made in Sept. 1986 - see further below). Three views montaged. 
Moderate-resolution.

scan of photo taken back in June 1985, this beacon, then on a weaker 382 kHz frequency, had a whimsical-looking (to us) "inverted coathangar" antenna not seen 
before, and had TWEB (Transcribed weather broadcasts). Sometime in the mid 1990's, MOG moved up to 404 kHz and has a much bigger signal (one of California's 
biggest signals now)due to tall vertical and top. cap. hat like the newer 305 ONO Oregon installation (see further below for those installations) or the power was

374 BOD - Bowman, North Dakota. BOD has guyed steel-lattice masts

Remington, John Seamons, and myself spent a couple of hours and many miles DFing down this beacon which is hard to spot from afar and located well away from 
the airport. We had to hike in a bit to the installation, and also the temperature was about 100 deg.-F. S. McGreevy, June 1985. CI327.jpg, 39,806 bytes.

2/4 COQl - Council, Idaho (McGreevy, 3/00] 


(former) 274 CQI, Council, Idaho. This beacon was notorious in the early to mid 1980's when it 
had severe 'negative keying’ on its carrier signal (its carrier dropped substantially when the ident tone was keying) leading to many reports of an unID "IAEIK" 
beacon, and CQI also radiated a well-heard negatively-keyed 7th-harmonic in the 160 meter ham band on 1918 kHz! In March 1988, I deviated 160 miles from my 
planned route in order to see this notorious beacon, which by then was behaving almost normally. CQI then had an older flat-top wire antenna supported by wooden 
poles. During 1997 - 1999, it's ident and carrier had not been detected in California, and I think it went off the air back then, as so many NDBs are today. Photo taken 
March 1988 by S. McGreevy. CQI274.jpg, 18,250 bytes.

nice tour of the facility and even partook in a group photo, holding two of my WR-3 receivers. At the time we were visiting, the transmiter was down for routine- 
maintenance that very day, and we listened to the beeping sounds of Omega-C Hawaii. - a truly fine group of people there in September 1993!

with a wire skirt - a hitherto unseen antenna type by me, but one that I am aware of that is replacing the wire antenna installations. 30-watt (listed) ONO gets out very 
well, often mixing with RO Roswell, New Mexico - once the two beacons are surrounded/buried by the slow-speed digital data sounds of the DGPS system, as both 
aeronautical beacons reside in the marine sub-band of 285-325 kHz. Happily in early 2018 305 ONO and RO (Roswell, NM) mix together as always in the clear now 
that all but the USCG DGPS beacons have left-air. I am not sure if ONO's signal level changed when the antenna replacement was made in the early 90s - it was a 
good signal back in 1988 and earlier, too. (February 2019: Still on-air and now in the clear again now that the 305 kHz Bakersfield DGPS station is off-air). (This 
antenna would make a fine LowFER beacon installation!). S. McGreevy, 9/93.

(former) 366 PLV, Wilsonville, Oregon. PLV was easily spotted on Interstate 5 about 30 miles south of Portland 
in 1988 and a pass-by in 1990. This beacon employed a guyed steel-lattice mast and 7-spoke top. capacitance hat without the skirt wire. I have not seen this particualr 
variation of an NDB antenna before. Please see next photo below, too. S. McGreevy 3/88. PLV366.jpg, 27,548 bytes.

Burns, Oregon earlier that week that the old 396 BNO (off-air now, replaced by a VOR) beacon transmitter was now in use at PLV! (Sheldon Remington and I had 
visited BNO back in May 1984 when it was on the air still). S. McGreevy, 3/88. PLV366B .jpg, 31,385 bytes.

392 PNY Pinedale, Wyoming BEST 19 a 


(former) 392 PNA, Pinedale, Wyoming. I liked PNA - it was often atop the 392 mixture that was 392 kHz for along time. Lately in 2014, PNA is quite alone on its 
frequency but happily still transmitting. PNA was always one of those beacons I wanted to visit someday, and so Gail and I on our big road tour of September 1993 
detoured a bit off the more direct highway to Jackson Hole and Yellowstone Nat. Park to visit PNA. PNA was right at the airport in an adjacent field. The beacon 
used a steel lattice mast, guyed, but with the top third of the three guy cables acting as a top capacitance hat/umbrella. PNW was new variant of an NDB antenna 
configuration I'd never seen before in the U.S. The gorgeous Wind River Range is in the far distance. S. McGreevy, Sept. 1993. PNA392 jpg, 45,174 bytes.

herein). The antenna look a bit dilapidated when Sheldon and I visited STI, and one of the two vertical wire feeds to the flat-top section of the wire antenna was 
broken. STI still is on the air but with a somewhat reduced signal since the early-mid 1980's, and I presume the antenna has ben replaced/updated. S. McGreevy, 5/84.

March 1988 visit to 304 “Y" Yaquina Head LH, Oregon - SPMcGreevy (former) 304 W, Yaquina Head 


Lighthouse (former marine NDB). ""W" was one of three 304 kHz, 50/10-format-marine-sequenced beacons on the Oregon Coast. It had higher power than the other 
small harbor marker beacons shown in the pictures on this page and employed a taller whip antenna. Nice photo of the Yaquina Head Lighthouse (taken in damp 
weather). This beacon is off the air too. S. McGreevy, March 1988. W304.jpg, 22,503 bytes. 


Fascinating note from Mark (AF6IM) about navigation using these former MARINE NDBs: 
Stephen, 


I really like your natural radio website a lot. You might want to include a link to my website (link at top of page) which has first hand information on using NDBs in 
California for commercial fishboat navigation: 


There was an extra feature on the Pt. Bonita NDB (and perhaps others) (the former 296 "B" Point Bonita Lighthouse beacon in Marin County - SpM) that allowed 
you to compute range in fog. All you needed was a stopwatch and a DF. The beacon was synched with the foghorn. You'd use a stop watch to measure the delay 
between arrival of the beacon tone and the foghorn and a simple speed of sound calc gave you range. I think I was perhaps the only person who actually used this in 
the 60s, but it was quite accurate and gave me position info at a critical point, entrance to S.F. I learned about it in some obscure pub like the Coast Pilot. It wasnt 
very obvious from reading the nav charts. 


I was sure sad to see the low power USCG local harbor NBBs disappear. I used them at Bodega Bay and Santa Cruz. Super useful for harbor entrance nav before 
GPS. They worked GREAT. 


Excerpt from my website: Manual RDFs were really hard to use accurately on a boat that was often yawing pitching and rolling. I longed for an ADF (such as the 
Bendix 555 or Jeppeson units), and an abundance of cheap surplus ARN 7 gear allowed me to get one dirt cheap. I liked ADF navigation and used it to full 
advantage. There was an AM broadcast station in Ft Bragg CA (KDAC 1230 with 1 kW - SpM) with a tower sited right on the coast that gave a very sharp-null 
which enabled me to always find the Noyo River entrance buoy even in pea soup fog. I'd start in slightly deeper water to avoid trouble, find the correct DF bearing 
that you'd see from the buoy and then ride the bearing into the charted depth that the buoy was anchored in. Bingo every single time even in nearly zero visibility. 


The loop compensator allowed you to zero out nearly all bearing distortion from the boats extensive metal commercial fishing rigging. It took some work to calibrate 
it properly but when set up right it worked like a charm. It was a brilliant design using a circular spring steel strip cam that you could vary the shape of with 
circumferentially spaced adjustment screws. The cam follower drove the loop selsyn and gave you corrected bearings on the I 82 indicator.

North S.F. Bay Area) pointed toward Oroville, but also toward a few other small airports in the northern Sacramento valley (colusa, etc.), and so we took a trip to find 
TST. After a day of enjoying the beautiful scenery and spring greenery along the way, we located TST at the Oroville airport. Close-in DFing was accomplished 
using only the loopsticks of two Sony ICF-7600D portable receivers. Later that day, TST went off the air (we did meet airport personnel inquiring about this beacon 
so they must have not known it was going and switched it off!). It later returned to the air for a few years as ident OVE. Photos by S. McGreevy March 1985.

Kirk writes on 25 March 2008: I have some good news regarding IP on 201 kHz. Frank informed me that this beacon is now back on the ai (ongoing as of January 
2018 monitoring - SpM. 


It had been off the air for several weeks but I checked last week and it was back in service. Not only that, it now appears to be on the air 24 hours daily. Formerly, it 
had turned off at 1900 MST every evening and remained silent all night until 0600 MST the following day. 


I wonder if this had been to conserve power, as IP receives its only power from a bank of large solar panels. (I know some other beacons that are that way, too!) I 
observed no above-ground power lines feeding the beacon in its desolate location in the Rainbow Valley, sandwiched between the Maricopa and Estrella Mountains 
in a sparse Sonoran Desert landscape. Now the beacon IP operates continuously. 


This shouldn't create a power shortage, as this is the sunniest time of the year in southern Arizona and there will now be more daylight than nighttime hours for the 
next six months. Of course, there may be unrelated technical reasons for the beacon having been QRT for a few weeks and changing its schedule. This is good news 
for you, as it gives you a better opportunity to hear IP during nighttime propagation conditions. 


The best time for you (SpM) to listen for it would most likely be just before sunrise, when noise from thunderstorms in the east has faded down but nighttime 
conditions are still in existence farther west.

: = a = 338 

RYN Ryan/Tucson, Arizona Kirk Writes in March 2008: The non-directional beacon RYN (338) is contained entirely inside the airport boundaries. As a result, access 
is blocked by a barbed wire fence and one can only approach the beacon within 100 yards. RYN is actually triple-protected by the barbed wire fence surrounding the 
air field, by a second wire fence surrounding the entire beacon's electronics and antenna structure, and by a third, small wire fence surrounding the antenna house and 


vertical wire that reaches up to the top hat. 


Prior to seeing RYN for the first time, I was actually expecting a more substantial antenna for a high-power beacon in its special 400-watt class. More specifically, I 
thought I might find a red and white vertical tower of several hundred feet (such as 254 SPK; 320 HTN; 368 SX; etc. - SpM). Instead, I (Kirk W.) found a very 
typical aeronautical NDB installation consisting of a vertical wire suspended from a two-conductor top hat strung between two wooden poles (rather hard to see in 
Kirk's photo, though). 


It was almost anticlimactic. Of course, it makes sense to keep any structures at an airport as low as possible. 


The two poles are perhaps 50 feet in height and the top hat consists of two horizontal wires, one above the other. The two horizontal top hat wires are parallel in the 
vertical, not horizontal plane. Very high voltage insulators are used to attach the top hat wires to the support poles. A small white cubical structure lies beneath the 
center of the top hat and the vertical wire appears to originate from it. 


Another, larger white cubical fiberglass-like structure lies 100 feet away near a VHF antenna structure. I wonder if the smaller structure contains just the tuning 
network and the larger structure contains the beacon electronics and its power supply. The larger cubical, boxlike structure was very reminiscent of the structure that 
exists at IP, 6 miles northwest of Mobile, AZ. (IP has been off the air since approximately Wednesday, February 6th, 2008. - back on - see above - SpM) RYN's 
antenna and top hat are basically identical in size and form to that used by IP. 


SpM writes: 338 RYN often battles it out at night throught the desert southwest with PBT Proberta/Red Bluff, California (audio file of PBT and RYN on 337 kHz a 


few nights ago around 19 March '08), which does employ a tall vertical mast antenna--I visited PBT in '85 - can't find the slide though... and NOTE: PBT left the air 
around December 2012. SpM

A scan of four photos of the of the rather spartan but brand-new "studio" and transmitter shack of (in testing-phase) 1060 KAHU 
Hilo, Hawaii Island, photographed during my time in Hilo when I was doing a lot of DXing there on LW and MW, and was a member 
of the Big Island Amateur Radio Club in Hilo - a fine bunch then! I also had fun with Dean Manley, KH6B doing initial field-strength 
measurements of KAHU all over the area during September 1986. SpM. - just 10 miles from KAHU, Mexico City creamed their 
signal and even in north Hilo the 200 kW Mexican station (en La Grande Ciudad de Mexico) could be heard underneath KAHU. 
Ground conductivity in the region was measured via field-strength curves at (only because of poor ground-conductivity lava 
terrain/geology) = ~0.3 mmhos! - SpM. Additionally, KAHU employed only a 1/5 wave tall mast due to close proximity to Hilo 
Airport (Gnl. Lyman Field) and could only put out a bit over 900 watts, also (nominally 1 kW). 1060 KAHU Hilo recorded with 
Hawaiian DJ_during their October 1986 testing phase - recorded at 667 Wainaku Avenue, Hilo by SP McGreevy
